Use the printable below to work your way up by 10 seconds each day, eventually reaching a 5 minute wall sit at the end of the month.
How To Do a Wall Sit
1) Position your back against a sturdy wall, walk your feet forward about 2 feet and position them hip-width apart.
2) Slide your back down the wall until your hips are at the same height as your knees (your thighs should be parallel with the ground).
3) Press your weight into your heels, relax your shoulders and squeeze your glutes. Hold this position for the allotted time.
